Resolved as I was to keep the mysterious appointment which summoned me to London at the month's end, Mr. MacGlue's suggestion met with no opposition on my part. It had, to my mind, the great merit of obviating the necessity of a second separation from my mother--assuming that she approved of the doctor's advice. I put the question to her the same day. To my infinite relief, she was not only ready, but eager to take the journey to the South. The season had been unusually wet, even for Scotland; and my mother reluctantly confessed that she "did feel a certain longing" for the mild air and genial sunshine of the Devonshire coast. We arranged to travel in our own comfortable carriage by post--resting, of course, at inns on the road at night. In the days before railways it was no easy matter for an invalid to travel from Perthshire to London--even with a light carriage and four horses. Calculating our rate of progress from the date of our departure, I found that we had just time, and no more, to reach London on the last day of the month. I shall say nothing of the secret anxieties which weighed on my mind, under these circumstances. Happily for me, on every account, my mother's strength held out. The easy and (as we then thought) the rapid rate of traveling had its invigorating effect on her nerves. She slept better when we rested for the night than she had slept at home. After twice being delayed on the road, we arrived in London at three o'clock on the afternoon of the last day of the month. Had I reached my destination in time? As I interpreted the writing of the apparition, I had still some hours at my disposal. The phrase, "at the month's end," meant, as I understood it, at the last hour of the last day in the month. If I took up my position "under the shadow of Saint Paul's," say, at ten that night, I should arrive at the place of meeting with two hours to spare, before the last stroke of the clock marked the beginning of the new month. At half-past nine, I left my mother to rest after her long journey, and privately quit the house. Before ten, I was at my post. The night was fine and clear; and the huge shadow of the cathedral marked distinctly the limits within which I had been bid to wait, on the watch for events. The great clock of Saint Paul's struck ten--and nothing happened.
